Technical Field
[0001] The present invention relates to the technical field of soil remediation detection, and in particular to a soil remediation detection device and a detection method. Background Art
[0002] Soil remediation refers to the use of a series of technologies and methods to improve or restore the quality and function of contaminated or degraded soil so that it can be suitable for plant growth and ecosystem recovery. Soil remediation not only helps to improve soil productivity, but also protects groundwater, improves the ecological environment and promotes sustainable development. Among them, soil density testing is particularly important, which determines whether the soil can continue to be used, so soil sampling and testing is required.
[0003] At present, the commonly used method for density detection is to adopt the drilling sampling method to take out the soil sample block, and then fill the pit of the taken sample block with test sand, and judge the density of the soil by observing the penetration of the test sand. The drilling sampling process requires specific equipment to complete.
[0004] There are many types of existing drilling and sampling equipment, including rotary drilling machines and ring knife cutting and drilling equipment. For example, the announcement number CN118294196A discloses a drilling and sampling device for road construction inspection, which includes a base plate, a drilling and sampling mechanism, a filling and pouring mechanism and a dust-proof spray mechanism. Moving wheels are installed at the bottom corners of the base plate, a push rod frame is fixedly provided near the rear of the top of the base plate, a lead screw is rotatably connected to the middle of the top front of the base plate, and the top of the lead screw is rotatably connected to the top plate, and vertical poles are fixedly distributed between the top plate and the base plate, a motor two is installed above the horizontal plate one, the drilling and sampling mechanism is installed at the bottom outer end of the horizontal plate three, the filling and pouring mechanism is arranged above the horizontal plates two and three, and the dust-proof spray mechanism is arranged below the horizontal plates two and three.
[0005] The drilling and sampling device for road construction detection is suitable for road construction detection. It automatically controls the height for drilling and sampling, and can adjust the position of the drilling and sampling at multiple angles. After drilling and sampling, the sample can be firmly fixed to prevent it from loosening. However, the drilling and sampling device will generate large-scale vibrations during drilling, which affects the drilling efficiency. At the same time, the vibration will also cause the hole wall of the borehole to be uneven, affecting the accuracy of the subsequent sand filling detection. The method of cutting and drilling with a ring knife can ensure the flatness of the inner wall of the borehole and reduce the probability of soil falling on the side wall of the inner wall. However, during the drilling and cutting process with a ring knife, the ring knife needs to be inserted upright into the soil, and then the soil inside the ring knife is excavated, which is inconvenient to operate and inefficient. At the same time, when the ring knife is pressed into the soil, the side of the ring knife will directly press against the soil, which will cause the hole wall to be compacted. During the sand filling detection, the amount of sand filling will be reduced, thereby increasing the density and causing deviation in the detection accuracy. Therefore, the present application provides a drilling and sampling device for road construction detection to meet the needs.
[0006] Therefore, a new type of soil remediation detection equipment can be used to solve the shortcomings of the existing technology. Summary of the invention

[0020] The present invention also provides a soil remediation detection method, comprising the above-mentioned soil remediation detection device, and further comprising the following steps:
[0021] S1. First, place the base on the top of the soil to be sampled, then adjust the base to be horizontal, and then drive the connecting rod to rotate through the rotating assembly, thereby driving the connecting block to rotate. The rotation of the connecting block will drive the pad to rotate, thereby driving the rotary drilling barrel to rotate. At the same time, open the multi-stage hydraulic rod, which will drive the control cabinet to move downward, thereby driving the rotating assembly to move downward. At this time, the rotary drilling barrel will move downward and rotate to perform the drilling operation of the rotary drilling barrel.
[0022] As the rotary drilling drum drills forward, the loose soil on the inner wall of the hole can be scraped off, and the compacted soil on the inner wall can be scraped off to keep the inner wall smooth and ensure the permeability of the inner wall.
[0023] S2. After the rotary drilling barrel is drilled, the operation of the multi-stage hydraulic rod and the motor 1 is stopped, and then the rotating assembly and the driving assembly are started. The rotating assembly will rotate the spiral cutting blade on the receiving barrel, thereby cutting the soil inside the rotary drilling barrel, and the cut soil is brought into the receiving barrel for collection. While the receiving barrel rotates, the driving assembly will push the receiving barrel downward to realize the drilling of the receiving barrel.
[0024] S3. When the receiving cylinder moves to the bottom of the rotary drilling cylinder, close the rotating assembly and the driving assembly, rotate the shaft, and the rotation of the shaft drives the spiral blade to rotate, so that the soil in the receiving cylinder is brought from the rotary drilling tube to the discharge pipe, and then the soil is discharged through the discharge pipe. After the soil is discharged, start the multi-stage hydraulic rod to remove the soil rotary drilling cylinder from the hole. At this time, the inner wall and bottom of the hole are flat.
[0025] Compared with the prior art, the present invention has the following advantages:
[0026] 1. By setting up a base, a slide rail and a counterweight box, the vibration amplitude can be reduced during the drilling process to keep the rotary barrel stable and improve the uniformity of the hole wall. At the same time, the soil to be excavated can be wrapped inside the rotary barrel during drilling, and the side wall of the rotary barrel can be attached to the wall of the drill hole, which can effectively avoid the probability of soil falling off the hole wall and reduce the subsequent cleaning process, thereby improving the efficiency of drilling sampling.
[0027] 2. By opening strip holes on the inner wall of the rotary drilling tube and setting a blade in the strip hole, the inner wall of the hole can be cut during the drilling process, and the inner wall of the hole can be scraped by cutting. This avoids the situation where the rotary drilling tube directly contacts the inner wall of the hole and causes the soil on the inner wall to be compacted, ensuring the permeability of the inner wall of the hole, thereby improving the accuracy of detection.
[0028] 3. By setting a storage cylinder, a spiral cutting blade, cutting teeth and a second blade, the soil after rotary drilling can be cut and broken up and stored in the storage cylinder, and then the spiral blades and the shaft rod are used to bring the broken up soil out of the storage cylinder, and then the rotary drilling cylinder is discharged through the discharge pipe. The operation is convenient and the soil cleaning efficiency is high. When the rotary drilling cylinder is taken out, the soil inside the rotary drilling cylinder is cleaned and the rotary drilling cylinder can be taken out directly, which can effectively prevent the soil inside the rotary drilling cylinder from falling into the drilled hole, reduce subsequent cleaning operations, and improve drilling efficiency.
[0029] To sum up, the present invention adopts rotary drilling to drill holes, and uses blade one to scrape the inner wall of the hole to ensure the permeability of the inner wall of the hole. At the same time, the soil inside the rotary drilling barrel can be automatically cleared after drilling. The operation is convenient and the drilling efficiency is high. In addition, blade two is used to scrape the bottom of the hole, and the scraped soil is brought into the storage barrel to keep the hole relatively clean and reduce the impact of fallen soil and uneven bottom on detection.

[0055] An inner cylinder 25 is fixedly installed in the middle of the storage cylinder 18, a feed port 32 is opened on the storage cylinder 18, and a discharge hole is opened on the inner cylinder 25. When the storage cylinder 18 rotates, the dispersed soil will enter the storage cylinder 18 through the feed port 32, and then be discharged through the discharge hole. A plurality of through holes are opened at the bottom of the storage cylinder 18, and a blade 27 is fixedly installed in each through hole. The cutting end of each blade 27 extends out of the through hole and is lower than the bottom surface of the storage cylinder 18. At the same time, the soil cut by the blade 27 will enter the storage cylinder 18 through the through hole and will also be discharged through the discharge hole.
[0056] The rotary excavation tube 14 is connected with the discharge hole, and the discharge tube 12 is rotatably connected on the rotary excavation tube 14. A shaft rod 17 is rotatably installed in the rotary excavation tube 14. A support frame is installed on the connecting block 7 through a telescopic rod. A limit sleeve 28 is fixedly installed on the support frame. The limit sleeve 28 is slidably connected with two of the support rods 10. A fixed block is fixedly installed on the limit sleeve 28, and the fixed block is fixedly connected to the discharge tube 12. A driving mechanism is installed between the support frame and the shaft rod 17. As the rotary excavation tube 14 moves, the discharge tube 12 will be driven to move, thereby driving the limit sleeve 28 to slide on the support rod 10, and the telescopic rod will be extended (when the telescopic rod is extended, the limit sleeve 28 and the discharge tube 12 move downward, refer to Figure 5 ).
[0057] The driving mechanism includes a motor 16 fixedly mounted on the support frame. The driving end of the motor 16 adopts a hexagonal design. The end of the shaft 17 close to the motor 16 is provided with a hexagonal groove that matches the driving end of the motor 16. The purpose of adopting this design is to facilitate the disassembly between the motor 16 and the shaft 17. The shaft 17 and the driving end of the motor 16 are fixedly connected by a snap-fit. A spiral blade 22 is fixedly mounted on the shaft 17, and a sealing plate 23 is fixedly mounted on the bottom of the storage tube 18. The shaft 17 and the sealing plate 23 are rotatably connected. A driving component that matches the rotary digging tube 14 is installed on the connecting block 7. The rotation of the driving end of the motor 16 will drive the shaft 17 to rotate, thereby driving the spiral blade 22 to rotate. During the rotation of the spiral blade 22, the rotary digging tube 14 remains fixed (or the rotation speed of the spiral blade 22 is greater than the rotation speed of the rotary digging tube 14), so that the soil in the storage cylinder 18 can be brought to the discharge pipe 12 through the rotary digging tube 14 by the spiral blade 22, and then the soil is discharged through the discharge pipe 12 (the bottom of the storage cylinder 18 is designed in a funnel shape, so that the soil in the storage cylinder 18 will automatically enter the rotary digging tube 14 under the action of gravity, and the spiral blade 22 can be used to bring all the soil in the storage cylinder 18 out, and at the same time, a cutting hole is also opened on the sealing plate 23, and a cutting knife is installed in the hole, which can bring the soil under the sealing plate 23 into the storage cylinder 18, and the spiral cutting blade 24 is used to bring the soil under the spiral cutting blade 24 into the storage cylinder 18, and the blade 2 27 is used to bring the soil under the storage cylinder 18 into the storage cylinder 18).

[0059] The specific operation steps of this device are as follows:
[0060] First, place the base 1 on the upper part of the soil to be sampled, and then adjust the base 1 to be horizontal (this part is the existing technology and will not be elaborated here), and then turn on the motor 5. The rotation of the driving end of the motor 5 will drive the connecting rod 9 to rotate, thereby driving the connecting block 7 to rotate. The rotation of the connecting block 7 will drive the pad 11 to rotate through the support rod 10, thereby driving the rotary drilling barrel 8 to rotate. At the same time, turn on the multi-stage hydraulic rod 3, which will drive the control cabinet 4 to move downward, thereby driving the motor 5 to move downward. At this time, the rotary drilling barrel 8 will move downward and rotate to perform the drilling operation of the rotary drilling barrel 8.
[0061] As the rotary drilling tube 8 drills forward, the blade 21 on the side wall of the rotary drilling tube 8 will scrape off the loose soil on the inner wall of the hole, and at the same time scrape the compacted soil on the inner wall to keep the inner wall flat and ensure the permeability of the inner wall.
[0062] After the drilling of the rotary drilling tube 8 is completed, the operation of the multi-stage hydraulic rod 3 and the motor 1 5 is stopped, and then the electric push rod 13 and the motor 3 19 are turned on. The rotation of the driving end of the motor 3 19 will drive the gear 1 29 to rotate, thereby driving the gear 2 30 to rotate. The rotation of the gear 2 30 drives the rotary drilling tube 14 to rotate, thereby driving the storage tube 18 to rotate. The rotation of the spiral cutting blade 24 on the storage tube 18 will cut the soil inside the rotary drilling tube 8. At the same time, the blade 2 27 at the bottom of the storage tube 18 will also cut the soil in the rotary drilling tube 8, and the cut soil will be brought into the storage tube 18 for collection. While the storage tube 18 rotates, the electric push rod 13 will push the storage tube 18 to move downward, thereby realizing the drilling of the storage tube 18.
[0063] When the storage cylinder 18 moves to the bottom of the rotary drilling cylinder 8, the blade 27 is in contact with the bottom of the hole, and then the motor 3 19 and the electric push rod 13 are turned off, and then the motor 2 16 is turned on. The rotation of the driving end of the motor 2 16 will drive the shaft 17 to rotate, and the rotation of the shaft 17 drives the spiral blade 22 to rotate, thereby bringing the soil in the storage cylinder 18 from the rotary drilling tube 14 to the discharge pipe 12, and then the soil is discharged through the discharge pipe 12. After the soil is discharged, the motor 2 16 is turned off, and the multi-stage hydraulic rod 3 is started to remove the soil rotary drilling cylinder 8 from the hole. At this time, the inner wall and the bottom of the hole are flat.
